64784634 ÷ 505 
Our goal is to divide 64784634 by 505.

Step 1:
The number 505 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 505

On to step 2:
The number 505 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (7) from the dividend, add it to 64, then carry on: 647 / 505

Going ahead to step 3:
505 goes into 647 1 times with a remainder of 142.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 505 from 647 and we're left with 142.
Append the next digit (8) from the dividend to 142 and continue with: 1428 / 505

Advancing to step 4:
505 goes into 1428 2 times with a remainder of 418.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1010 away from 1428, we end up with 418.
Grab the next digit (4) from the dividend, add it to 418, then carry on: 4184 / 505

Moving on to step 5:
505 can be fit into 4184 8 times, resulting in a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 128.0
If we take 4040 away from 4184, we end up with 144.
Include the next digit (6) from the dividend after 144, then repeat: 1446 / 505

On to step 6:
1446 divided by 505 is 2 with a remainder of 436.
Put 2 as the next digit of the answer. 
Result so far: 1282.0
Deduct 1010 from 1446 and we're left with 436.
Take the next digit (3) from the dividend and append it to 436, then repeat: 4363 / 505

Step 7:
4363 divided by 505 is 8 with a remainder of 323.
The next digit of our result is 8. 
Result so far: 12828.0
If we take 4040 away from 4363, we end up with 323.
Include the next digit (4) from the dividend after 323, then repeat: 3234 / 505

Going ahead to step 8:
If we divide 3234 by 505, we get 6 and a remainder of 204.
Write down 6 as next digit of the result. 
Result so far: 128286.0
Deduct 3030 from 3234 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 9:
If we divide 2040 by 505, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 128286.4
The remainder is 20 after subtracting 2020 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
If we divide 200 by 505, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 128286.4
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 11:
When dividing 2000 by 505, we get 3 with a remainder of 485.
The next digit of our result is 3. 
Result so far: 128286.403
Subtracting 1515 from 2000 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 12:
505 goes into 4850 9 times with a remainder of 305.
The next digit of our result is 9. 
Result so far: 128286.4039
Subtract 4545 from 4850 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 13:
3050 divided by 505 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 128286.40396
The remainder is 20 after subtracting 3030 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
505 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 128286.40396
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 15:
If we divide 2000 by 505, we get 3 and a remainder of 485.
The number 3 becomes the next digit in our result. 
Result so far: 128286.4039603
The remainder is 485 after subtracting 1515 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 16:
The number 505 fits into 4850 9 times, leaving a remainder of 305.
Write down 9 as next digit of the result. 
Result so far: 128286.40396039
Subtracting 4545 from 4850 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

After the division, we end up with 128286.40396039 and a remainder of 3.05e-07.
